Problems solved by technology

[0007] Although each of the above devices can be operated remotely, their range of motion is generally limited
Steering mechanisms are also cumbersome to use, as in the catheter of Boury et al., each wire must be pulled individually to shape the catheter

Embodiment Construction

[0046] As described in greater detail herein, articulation link systems and mechanisms are provided that may form or incorporate or constitute a variety of devices. A chain link system can be formed from a combination of individual chain links. Articulation mechanisms according to the invention generally include pairs of links and at least one set of cables connecting at least one pair of separate links. As used herein, the term "link" refers to a system of links or a discrete part of an articulation mechanism that is movable relative to another discrete part of the system or mechanism. In some embodiments, a link may correspond to another separate portion or defined area at an opposite end of the mechanism. The links are usually barrel shaped, but need not be. The links are generally aligned along the longitudinal axis of the mechanism. In some embodiments, the link system may include a plurality of links, at least two of which are separated by bushings.

Abstract

Articulating mechanisms, link systems, and components thereof, useful for a variety of purposes including, but not limited to, the remote manipulation of instruments such as surgical or diagnostic instruments or tools are provided. The link systems include links wherein at least two adjacent links are pivotable relative to one another around two distinct pivot points. Mechanisms for locking the links are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 60 / 577,757, filed June 7, 2004, the contents of which are hereby incorporated by reference into this disclosure. technical field [0003] The present invention relates to link systems and applications thereof, including remote guidance and manipulation of surgical or diagnostic instruments and tools. Background technique [0004] The ability to easily steer, guide, and / or operate instruments and tools remotely is of interest in many industries and applications, especially where it is desired to direct the instruments or tools to places where manual guidance is not easy or would present a risk or hazard in the working space. These can include situations where the application tool or instrument is difficult to reach the target site, such as certain surgical procedures where manual access to the target site is limited, or the manufacture or repair of m...
